Summary and assessment of the data on bat fauna of south-western Moravia are given in the paper, including all available older findings from the period 1956–1990 and larger material obtained by survey carried out mostly in the Znojmo and Třebíč districts in 1990–2003. The study area of about 4500 km2 is situated at the boundary between the Hercynian and Pannonian biogeographical subprovinces. In total, 19 bat species (83% of species of bat fauna of South-Moravian lowlands and 79% of species of bat fauna of the Czech Republic) have been recorded in the region. Plecotus austriacus, Myotis myotis, Myotis daubentonii, Plecotus auritus, Nyctalus noctula and Eptesicus serotinus are the most widespread species (found in more than 70% of 11.2×12 km grid squares, used in mapping of fauna in the Czech Republic); Myotis mystacinus, Barbastella barbastellus, Myotis emarginatus, Rhinolophus hipposideros, Pipistrellus pipistrellus, Myotis brandtii and Myotis nattereri are less often recorded but still probably common species (4063% of squares); Nyctalus leisleri, Vespertilio murinus, Pipistrellus nathusii and Eptesicus nilssonii are less common species (25–34% of squares); and Pipistrellus pygmaeus and Myotis bechsteinii are rare species (up to 25% of squares). E. nilssonii is the only species which respects the biogeographical boundary between the European deciduous forest province (Hercynia) and the European steppe province (Pannonia), running across the study area. Similar distribution pattern is found in V. murinus. In R. hipposideros and M. emarginatus, the western limits of distribution range are shifted more towards forested areas of the Bohemian-Moravian Highlands. None of the two species exceeds higher altitudes of the Bohemian-Moravian Highlands to Bohemia and both form relatively strong and viable populations in patchy habitats of the “transitional” belt along the biogeographical boundary. Differences in population gradient between the provinces have been found also in three other, synanthropic and rather thermophilic species, M. myotis, E. serotinus, and P. austriacus.
